Getting too many problems when running 'npm install'

Hello,

When I try to run ‘npm install’ on a project it gives me these errors (I know they’re warnings, but the project doesn’t work because of them):

npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but npm-shrinkwrap.json was generated for lockfileVers

Have tried to upgrade/downgrade dependencies locally and globally, but nothing worked. I have tried to upgrade/downgrade node.js, tslint, npm and typescript.
Have also tried to clean the cache.

This is my ionic info:

global packages:

    @ionic/cli-utils : 1.5.0
    Cordova CLI      : 7.0.1
    Ionic CLI        : 3.5.0

local packages:

    @ionic/app-scripts              : 2.0.2
    @ionic/cli-plugin-cordova       : 1.4.1
    @ionic/cli-plugin-ionic-angular : 1.3.2
    Cordova Platforms               : none
    Ionic Framework                 : ionic-angular 3.5.2

System:

    Node       : v6.11.1
    OS         : Windows 8.1
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed
    npm        : 5.3.0

Have been stuck in this for a week without getting any further.

Can anybody tell me why it isn’t working, and what I should do to fix these problems? :slight_smile:

Your copies of Angular Core and Angular Fire are super out of date.

  1. Physically delete, into the recycling bin, node_modules.
  2. In command line: npm cache clean --force
  3. Install nvm-for-windows.
  4. Use nvm to install any version of Node that is the LTS or more recent
  5. Install Ionic and Cordova from scratch in that clean Node install.
  • Do not take any installation steps as administrator. (You might need to give admin permissions to delete node_modules in step 1. That’s the only time you do that. Otherwise a corrupt install will be hard to remove.)

@AaronSterling; Is installing nvm necessarily ? Cause npm worked a week ago. Have done the first 2 steps

No, but it’s one of the strongest possible recommendations I can make when dealing with npm. You can have multiple versions installed at once, switch effortlessly between them, and (most importantly) everything is stored in a single directory in your home that can easily be isolated if any weird corruption happens. I consider @AaronSterling’s suggestions here to be absolutely spot-on.

Then how do I fix the problems I’ve with npm? :slight_smile:

They will probably already be fixed after you uninstall node (which includes npm) and install nvm to install a new node (which will again install a new npm).
